These openings need not be any larger than necessary in order to allow the conveyer to pass without interference.

From the foregoing description, the use and operation of my improved construction will be readily understood. It may be assumed that the carcasses whichl will designate by the numeral a l move downwardly into the room where the steam chamber is located, on a track 47 of any suitable construction, and which is arranged to termi nate just forward of the front end of the chamber. As the carcasses move downwradly or into the inclosure where the steam chamber is located upon this track, they are suspended from the track from one leg, by the employment of suitable shackles not shown. As the carcasses approach the forward end of the steam chamber upon this track and before they reach the inwardly opening doors, the person in charge of this work connects a shackle of the construction shown in Fig. I) with the free hind leg of each carcass, by wrapping the chain 31 around this leg and connecting the hook 32 with one of the links and connecting the hook portion 28 of the shackle with one of the rungs 27 of. the conveyer. As soon as this is accomplished, the shackle which was connected with the other leg of the carcass and which was riding upon the track 47, automatically disengages itself from the track as the latter terminates just in front of the upper portion of the steam chamber. The carcass is then carried through the in strumentality of the conyeyer, against the inwardly opening front doors of the chambhiy'and passes thereinto and therethrough. As soon as one carcass enters the chamber another one is connected in front of the chamber with another rung of the conveyer in the same manner. and in this way the operation of passing carcasses through the steam chamber may be continuous and uninterrupted as long as may be required, or until the supply in the killing room is exhausted. This chamber may be of any suitable length that may be required in order to properly loosen the bristles of the carcasses as they are passing through the chamber, through the instrumentality of the steam, hot vapor or other fluid which it may be desired to apply. As each carcass passes out of the chamber 'at its rear end and the outwardly opening doors swing inwardly,

the upper extension 30 of the shackle engages the stop 34, which acts to move the hook extremity of the shackle far enough rearwardly to disconnect it from the rung of the conveyor, allowing the carcass to drop upon a downwardly inclined platform 48 through whose agency it passes to the desired'room or locality where the dressing of the carcass is to be continued.

Having thus described my invention, what I claim is,

1. In combination, a steam chamber having swinging doors at its opposite ends, means extending through the upper portion of the chamber and projecting therefrom at both ends for carrying carcasses through the chamber, and means for introducing steam or vapor into'the lower portion of said chamber at points in close proximity to the entire path of travel of the lower extremities of the said carcasses.

2. In combination, a steam chamber, means extending through the upper portion of said chamber for carrying carcasses there'- through, and means located in the lower part of the chamber for introducing steam or vapor therein, said means extending approximately the entire length of the said chamber and lying in close proximity to the path of travel of the lower extremities of the carcasses.

3. In combination, a steam chamber, means extending through the upper portion of said chamber for carrying carcasses therethrough, a pipe located in the lower part of the chamber and extending longitudinally thereof, said pipe being connected with a suitable steam source, provided with perforations throughout its length and lying in proximity to the path of traycl of the.

lower extremities of the carcasses.

4. In combination, a steam chamber, means extending through the upper portion of said chamber for carrying carcasses therethrol'igh, pipes located in the lower portion of said chamber andv extending approximately the entire length thereof, said pipes being provided with means at points, throughout their length for introducing steam or vapor into the path of travel of the lower extremities of said carcasses.

In testimony whereof 1 aliix my signature in presence of two witnesses.
